The Flowserve Logix 3200MD is a digital HART positioner that uses piezo technology for reliable and accurate control of pneumatic actuators. It accepts a 4–20 mA input signal and provides precise valve positioning with simple local calibration via buttons and DIP switches. The positioner is known for its low air consumption, good repeatability, and straightforward setup, making it a solid choice for many general process control applications.
